Quantum Predator-Prey Games ⚡ экспресс
Scientists have created a quantum analog of the predator-prey model (like foxes and rabbits) on an array of Rydberg atoms. On microsecond timescales, atomic excitations play the roles of predators and prey, exhibiting stable cycles. This opens the door to simulating ecosystems in quantum labs. Could other ecological rhythms emerge in atomic "jungles"?
In nature, everything is cyclical: hares multiplied — foxes thrived — hares ran out — foxes died off — and the cycle repeated. This 'predator-prey' model was invented a century ago, and it works everywhere: from chemistry to economics. Physicists have now brought this storyline to the atomic stage. They built a lattice of hydrogen atoms and inflated them to giant sizes — into a Rydberg state, named after Johannes Rydberg. These giant atoms sense each other from afar and act out the same drama: some states become 'predators,' others 'prey.' Quantum laws don't break but rather reinforce the cycle. A natural rhythm emerges, resistant to disturbances. Stray quantum jumps only add a light ripple that smoothes out when there are many atoms — like noise in a large orchestra.
This is how scientists harness non-equilibrium quantum effects for the ultrafast simulators of the future.
🎯 The predator-prey model is even applied to star systems, explaining fluctuations in cosmic ray populations.
🎬 In the novel 'Dune,' the desert planet's ecology follows cycles reminiscent of the Lotka-Volterra model.
